How we work

Tool processing

Launch tools process text and files in your browser. File tools use a Select / drop stage so you can pick JPEG, PNG, or PDF files locally. We do not upload Word Counter text, Case Converter text, images, or PDFs to our servers for those tools. Downloads create a new file; your original stays on your device.

What we do not claim

  • We do not claim to remove every possible metadata field or hidden trace.
  • We do not offer AI detector bypass or provenance forgery.
  • We do not promise AdSense approval or search rankings.

Content process

Guides are researched, written for a specific reader problem, and reviewed for accuracy before publishing. See the editorial policy.

Security basics

We validate file signatures, enforce size and dimension limits, and refuse encrypted or digitally signed PDFs in the first PDF cleaner release so signatures are not silently invalidated.
